Do carpenter bees sting? Nobody likes being stung by bees. When you see huge carpenter bees nesting around your house, it can be very intimidating.
Female carpenter bees have stingers and will sting if provoked. Thankfully they are not aggressive but caution should be taken all the same. Females can be identified by their black head.
Male carpenter bees do not have stingers but will be quite aggressive when defending the nest. If you approach an occupied carpenter bee nest, you may very well be buzzed by the male. Males can be identified by the white/yellow markings on their heads.
